The name indicates a name of the connected external device, the product ID indicates a product ID of the connected external device, and the vender ID is an ID of a manufacturing company which manufactures the external device.

The package management unit 301 may configure external device support information for each application program into a database. The package management unit 301 may confirm whether a specific application program is installed in the electronic apparatus 101. The specific application program may be received from an external server or another electronic apparatus wirelessly or wiredly. For example, when the specific application program is installed, the package management unit 301 may detect package meta data from package data of the specific application program, and detect the external device support information from the detected meta data. The package meta data may be attribute information, and may include at least one of contents of information about the package data, user information, a right condition, a use condition, use history information, and the external device support information. For example, the package meta data may be a “Manifest.xml” file of the specific application program. In another example, when the package meta data is the “Manifest.xml” file of a specific application program as shown in FIG. 6 , the package management unit 301 may detect external device support information 601 included in the package meta data. The external device support information 601 is information indicating the type of external device supported by the specific application program, and may include one or more of an ID 609, a condition name 617, a class 603, a subclass 605, a protocol 607, a name 611, a product ID 613, and a vender ID 615, and store each constituent element of the external device support information in a form of a table like Table 1 or another similar and/or suitable form.

Further, the package management unit 301 may store, for example, the external device support information so as to correspond to the specific application program in the memory unit 207. For example, when the package meta data is “Manifest.xml” as in FIG. 6 , the package management unit 301 may configure the external device support information into a table like Table 1 or another similar and/or suitable form, and store the external device support information.

For example, the package management unit 301 may generate the external device support information corresponding to the application program for each application program. When the package management unit 301 is connected with the external device, the package management unit 301 may generate an application program list including an application program identifier supporting the connected external device, and transmit the generated application program list to the application program management unit 305. That is, when the package management unit 301 is connected with the external device, the package management unit 301 may receive the external device information about the connected external device from the device management unit 303. The package management unit 301 may search for one or more application programs supporting the external device based on the external device information and the pre-stored external device support information for each application program. The package management unit 301 may generate an application program list including one or more application program identifiers indicating the found one or more application programs, and transmit the generated application program list to the application program management unit 305. Here, the application program identifier may be an application program name.

For example, the package management unit 301 may search for one or more elements of the external device support information including one or more elements among all of the elements included in the external device information in the external device support information for each application program. When the package management unit 301 searches for one or more elements of the external device support information including the one or more elements, the package management unit 301 may generate an application program list including one or more application program names corresponding to the found external device support information.

For example, the package management unit 301 may search for one or more elements of the external device support information including all of the elements included in the external device information in the external device support information for each application program. When the one or more elements of external device support information including all of the elements is found, the package management unit 301 may generate an application program list including one or more application program names corresponding to the found external device support information.

The application program management unit 305 may execute an application program supporting an external device. For example, the application program management unit 305 may receive the application program list from the package management unit 301, and may confirm whether the number of found application programs is plural by analyzing the received application program list. For example, when the number of found application programs is one, the application program management unit 305 may automatically execute a specific application program corresponding to a specific application program identifier included in the application program list. In another example, when the number of found application programs is plural, the application program management unit 305 may display a plurality of application program identifiers included in the application program list. For example, the application program management unit 305 may display a pop-up window 703 including application program names and check boxes for receiving a selection of any one application program name among the application program names as in screen 701 in FIG. 7 .

For example, the application program management unit 305 may confirm whether any one application program identifier is selected among the plurality of displayed application programs by a user. For example, when a check box corresponding to a second application program is selected by a user among the check boxes included in the pop-up window 707 as in screen 705 of FIG. 7 , and “YES” 709 is selected by the user, the application program management unit 305 may determine that the second application program is selected.

Further, for example, when a specific application program identifier is selected, the application program management unit 305 may assign exclusive use authority for an external device connected to a specific application program corresponding to the selected application program identifier. Accordingly, an external device connected with another non-selected application program cannot be used. That is, the application program management unit 305 may execute the specific application program corresponding to the selected application program identifier. For example, when the second application program is selected as in screen 705 of FIG. 7 , the application program management unit 305 may assign exclusive use authority for a USB device connected to the second application program, and execute the second application program.

FIG. 4 is a flowchart illustrating a process of configuring USB support information into a database according to an embodiment of the present disclosure.

In this case, the specific application program may be received from an external server or another electronic apparatus wirelessly or wiredly.

In operation 403, the package management unit 301 may detect package meta data from package data of the specific application program, and detect external device support information from the detected package meta data. For example, the package metal data may be a “Manifest.xml” file of the specific application program. In another example, when the package meta data is the “Manifest.xml” file of the specific application program as in FIG. 6 , the package management unit 301 may detect external device support information 601 included in the package meta data. The external device support information 601 is information indicating the type of external device supported by the specific application program, and may include the ID 609, the condition name 617, the class 603, the subclass 605, the protocol 607, the name 611, the product ID 613, and the vender ID 615.

In operation 405, the package management unit 301 may store the external device support information so as to correspond to the specific application program. For example, when the package meta data is “Manifest.xml” like FIG. 6 , the package management unit 301 may configure the external device support information into a table like Table 1 or another similar and/or suitable form, and store the external device support information.

The name indicates a name of the connected external device, the product ID indicates a product ID of the connected external device, and the vender ID is an ID of a manufacturing company which manufactures the external device.

In operation 505, the package management unit 301 receives the external device information from the device management unit 303, and searches for one or more application programs which support the external device based on the external device information and the pre-stored external device support information for each application program. Accordingly, the package management unit 301 may generate an application program list including one or more application program identifiers indicating the found one or more application programs. Here, the application program identifier may be an application program name. Further, for example, the package management unit 301 may search for one or more elements of the external device information received from the external device in the external device support information for each application program. When the external device support information including the one or more elements of the external device information is found, the package management unit 301 may generate one or more application program lists corresponding to the found external device support information. The application program list may include a name of the connected external device.

In another example, the package management unit 301 may store a plurality of elements of external device support information including all of the elements of the external device information received from the external device. The package management unit 301 may search for one or more elements of external device support information including all of the elements included in the external device information in the external device support information corresponding to the application program. When the one or more elements of external device support information including all of the elements is found, the package management unit 301 may generate one or more application program lists corresponding to the found external device support information. The application program list may include a name of the connected external device.

Further, in operation 507, the application program management unit 305 may receive the application program list from the package management unit 301, and may confirm whether the number of found application programs is plural by analyzing the received application program list.

When the number of found application programs is plural, the application program management unit 305 may perform operation 511, otherwise, the application program management unit 305 may perform operation 509.

In operation 509, the application program management unit 305 may automatically execute a specific application program corresponding to a specific application program identifier included in the application program list.

In operation 511, the application program management unit 305 may display a plurality of application program identifiers included in the application program list, and then perform operation 513. For example, the application program management unit 305 may display the pop-up window 703 including application program names and check boxes, through which any one application program name is selectable among the application program names, as in screen 701 in FIG. 7 .

Further, in operation 513, the application program management unit 305 may confirm whether any one application program identifier is selected among the plurality of displayed application programs by a user. For example, when a check box corresponding to a second application program is checked among the check boxes included in the pop-up window 707 as in screen 705 of FIG. 7 , and “YES” 709 is checked, the application program management unit 305 may determine that the second application program is selected.

Further, in another example, the program management unit 305 may automatically select one among the plurality of application programs according to a predetermined priority. For example, when the found application program is the first application program and the second application program, the program management unit 305 may automatically select the first application program according to a predetermined priority (in a case where the first application program has a higher priority than the second application program). Accordingly, the program management unit 305 may receive exclusive use authority for the first application program, and execute the first application program. When the specific application program identifier is selected, the program management unit 305 may perform operation 515, otherwise, the program management unit 305 may repeatedly perform operation 513.

In operation 515, the program management unit 305 may assign exclusive use authority for the external device connected to the specific application program corresponding to the application program identifier selected so that non-selected other application programs do not use the external device, and then perform operation 517.

In operation 517, the application program management unit 305 may execute the specific application program corresponding to the selected application program identifier. For example, when the second application program is selected as in screen 705 of FIG. 7 , the application program management unit 305 may assign exclusive use authority for the external device connected to the second application program, and execute the second application program.

Referring back to FIG. 6 , the package meta data for a specific application program may include the external device support information 601. Here, the external device support information 601 is information indicating the type of external device supported by the specific application program, and may include at least one of the ID 609, the condition name 617, the class 603, the subclass 605, the protocol 607, the name 611, the product ID 613, and the vender ID 615.

Here, the ID 609 indicates an ID assigned in order to confirm the number of specific devices by which the specific application program is automatically executed. Further, the condition name 617 indicates the condition of the specific device for the automatic execution of the specific application program. For example, when the condition of the automatic execution of the specific application program is that the specific device is the external device, the condition name may be “usb-device” indicating that the specific device is the external device.
